From 13–15 October 2025, Ana M. Ferreira participated in the 2025 Conference of the ECUST–University of Aveiro Joint Research Center for Sustainable Chemistry and Materials, held at East China University of Science and Technology (ECUST) in Shanghai, China.

Representing the GreenPATH project, she delivered the presentation “Plastic Alchemy: Greener Approaches to Polymer Recycling”, showcasing recent advances in greener solvents and enzymatic routes for the circular recycling of engineering plastics.

The conference provided an excellent platform to strengthen research collaboration between ECUST and the University of Aveiro and to exchange ideas with scientists committed to sustainability and innovation in materials science.

From 20–24 July 2025, Ana M. Ferreira attended ICCT2025 | 27th IUPAC International Conference on Chemical Thermodynamics in Porto, Portugal. Representing the GreenPATH project, she presented the poster titled “Paving the way to a sustainable future: COSMO-RS as a tool to identify eutectic solvents for selective polymer dissolution”, showcasing computational thermodynamics (COSMO-RS) screening to predict solvent–polymer selectivity and guide sustainable polymer recovery processes. 

From June 22–27, 2025, Mariana Aguiar participated in the European Polymer Congress, held in Groningen, the Netherlands, which gathered international researchers working on polymer science and innovation.

Representing the GreenPATH project, she presented two posters: "Smart solvent design: using COSMO-RS to unlock selective polymer dissolution", demonstrating how computational solvent screening can improve the selectivity of polymer recovery processes; and "Enhancing the potential of laccase-driven biodegradation of polymers using biosolvents", which explored how alternative solvents can promote enzymatic depolymerisation.

These contributions highlight GreenPATH’s interdisciplinary approach to advancing sustainable polymer recycling through the integration of computational chemistry and biocatalysis. 

From June 15 to 20, 2025, Ana M. Ferreira participated in the Joint Meeting, the 14th International Symposium on Supercritical Fluids and the 9th International Solvothermal and Hydrothermal Association Conference, held in Bali, Indonesia, which gathered leading researchers in green chemistry, fluid-phase technologies, and sustainable material processing.

Representing the GreenPATH project, she delivered an oral presentation entitled "Plastic waste metamorphosis: greener solvents and enzymes for circular transformation". The presentation comprised two independent studies: one focused on COSMO RS guided screening of eutectic solvents for selective dissolution of commodity and bio based polymers, and the other on enhancing HDPE biodegradation through additive removal and enzymatic treatment with laccase.

These contributions addressed key conference topics such as green chemistry, sustainable feedstock utilization, and polymer processing, aligning with the event’s theme “Convergence Technology of the Green Future” and contributing to the discussion on innovative strategies for circular plastics management.

From May 12–16, 2025, Ana M. Ferreira participated in the International Symposium on Green Chemistry (ISGC 2025), held in La Rochelle, France, which brought together leading researchers in sustainable chemistry and circular economy.

Representing the GreenPATH project, she delivered an oral presentation entitled "Advancing polymer recycling: COSMO-RS-guided selection of eutectic solvents for selective dissolution", highlighting the use of computational tools to enable greener plastic recycling strategies. She also presented a poster on "The Role of Additives in the Enzymatic Degradation of High-Density Polyethylene", discussing how additive removal can enhance the biodegradation of plastic waste.

These contributions reflect GreenPATH’s commitment to developing sustainable solutions for polymer recovery and valorization.

Mariana I. S. Aguiar received the Best Poster Award at the 9th Green and Sustainable Chemistry Conference, held in Pune, India, from March 4–6, 2025.

Her award-winning poster, "Enhancing Plastic Waste Recycling: Investigating the Impact of Additives on Polymer Degradation via Laccase from Trametes versicolor", was co-authored with Andreia F. Sousa, Ana P. M. Tavares, Ana M. Ferreira, and João A. P. Coutinho.

The study demonstrates how the removal of additives from high-density polyethylene (HDPE) can significantly improve enzymatic degradation, contributing to more efficient and sustainable plastic recycling strategies.

Congratulations to the entire team on this remarkable achievement!

From March 4-6, 2025, members of our team participated in the 9th Green and Sustainable Chemistry Conference (9th GSCC), held in Pune, India. This international forum brought together leading researchers and innovators in sustainable chemistry to explore advances in polymer recycling, green solvents, energy storage, and biomass valorization.

Dr. Ana M. Ferreira, Dr. Filipe Sosa, and PhD candidate Mariana I. S. Aguiar contributed to the event with the following presentations:

• Oral presentation "COSMO-RS as a tool to identify eutectic solvents for selective polymer dissolution", showcasing computational approaches to guide greener polymer recycling strategies.

• Poster presentation "Enhancing the recycling of plastic waste by evaluating the impact of additives on the enzymatic degradation of polymers", which was awarded Best Poster of the conference. The work emphasized the role of additive removal in improving enzymatic depolymerization of HDPE.

These contributions highlight the team’s commitment to advancing sustainable polymer processing and promoting circular economy solutions within the GreenPATH initiative.
